Webwhere ψ(X) is the classical Chebyshev function. From the Brun–Titchmarch inequality (see [8, Theorem 6.6]) and the prime number theorem we can conclude that ψ(X +Y) −ψ(X) ≪ Y for Y ≥ Xθ with θ>1/2, which establishes Hypothesis 1.1 for any 0 Webwhen using the approach we already put to work for the coset Brun-Titchmarsh inequality in [14]. The surprise is that, though we seem to be using the same kind of sieve argument as when bounding the density from above, the additive consequences are distinct.
